Earthquake

　　1.Every year earthquakes are responsible for a large number of deaths and a vast amount of destruction in various parts of the world.Most of these damaging earthquakes occur either in a narrow belt which surrounds the Pacific Ocean or in a line which extends from Burma to the Alps in Europe.Some of the destruction is directly caused by the quake itself.An example of this is the collapse of buildings as a result of the quake itself.Other damage results from landslides or major fires which are initiated by the quake.

　　2.There are about a million quakes a year.Fortunately,however,not all of them are destructive.The intensity of an earthquake is measured on the Richter Scale,which goes from 0 upward.The highest scale recorded to date is 8.9.Major damage generally occurs from quakes ranging upwards from 6.0.

　　3.The actual cause of the quake itself is the breaking of rocks at or below the earth's surface.This is produced by pressure which scientists believe may be due to a number of reasons,two of which are the expansion and contraction of the earth's crust and continental drift.

　　4.In order to limit the damage and to prevent some of the suffering resulting from earthquakes,scientists are working on ways to enable accurate prediction.Special instruments are used to help people record,for example,shaking of the earth.Scientists are trying to find methods that will enable them to indicate the exact time,location and size of an earthquake.

　　5.Certain phenomena have been observed which are believed to be the signs of imminent earthquakes.These include strange behaviors of some animals,the changes in the content of mineral water,etc.The magnetic properties of rocks may also display special pattern before major earthquakes happen.

　　23.Paragraph 2 __________

　　24.Paragraph 3 __________

　　26.Paragraph 5 __________

　　A.Earthquake's Forecast

　　B.Historical Records of Earthquakes

　　D.of a possible earthquake

　　E.the unusual behaviors of some animals

　　F.the strong behaviors of human beings

　　参考答案：

　　23.C　本段简述在里氏震级表上反映出来的不同震级。

　　24.D　本段简述了地震的起因。

　　25.A　本段介绍了科学家为预测地震所做的一些工作。

　　26.E　本段介绍了震前可能会出现的一些异常情况。

　　27.A　句中的被动语态…is caused提示可能会跟一个by短语。

　　28.C　形容词加上enough后面常会跟一个动词不定式，文中第二段也讲到有些地震震级不高，不会造成重大破坏和伤亡。

　　29.D　动词warn后面跟against，或跟of，警告别人将有事情发生。

　　30.E　动词observin9后面应该有一个宾语，故应选一个名词短语。人类的行为变化跟地震并没有关系，因此F不是正确的选择。
